<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">casino city</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for reno that I've seen before include "Nevada city of Nero" , "Divorce capital of Nevada" , "Nevadan city" , "Nevada marriage and divorce centre" , "City in Nevada known for casinos and easy divorces" .)
